My set up is Vista Business 32bit and Outlook 2007 B2TR where my PST files
are stored on a local network drive.

When opening Outlook, I recieve the message:
"Cannot Start Microsoft Office Outlook. Cannot open the Outlook Window. The
set of folders cannot be opened. The file xxx\Outlook.pst cannot be accessed."

On going to the location of the pst file, I can rename, but not copy or move.
"Error 0x80070021: The process cannot access the file because another
process has locked a portion of the file."

There are no processes using this file as I have tried to access the same
file from another computer to the network drive. I have also tried to use
"unlocking" tools which say the file is not locked by any process.

It seems that Outlook didn't unlock the file after it was closed the last
time and has left it in a half-locked state.

I have tried to run the SCANPST application on it, however it too cannot
access it to scan it.

Are there any ideas to how this could be resolved? I have alot of emails in
these PST's and would prefer not to have to start from scratch.

I didn't know Microsoft didn't reccomend the use of pst files over a network,
I won't be doing it again, however, I cannot move these files to my computer
as it is locked.
